3 natures of the smaller number of pages to Under the foremost of the folding-rolls 31 form a permanent one of the larger number. 31*there is arranged the shaft 36 of the rotary Figure 1 of the drawings represents the deslitter, carrying three slitting-blades 37, only So livery end of a machine for making sixtyone of which is visible, for cutting the folded four-page signatures; Fig. 2, a vertical lonsheet transversely to the lines of fold into 35 gitudinal section at right angles to Fig. 1, four quarter-sheets which may be termed taken at about the middle of the width of the signature-sections. This rotary slitter is machine; Fig. 3, avertical sectional view, parof well-known kind and needs no particular allel with Fig. 2, of mechanism for operating description further than to say that-its blades the folding-blades; Fig. 4, a vertical section 37 runin grooves in the folding-roll 31* 4 parallel \vithFig. 1, taken on the line a 4 of above. Forward of the slitter are suitably Fig. 2; Fig. 5, a view corresponding with arranged (see Fig. 4) a folding-table 39, four portions of Figs. 1 and 4, but on a larger scale, parallel pairs of folding-rolls, two of which. 9 showing the insetting devices and parts of the pairs are designated 40 and two 40 and four stapling devices; Figs. 6, 7, 8, 9, side views of folding-blades 4d, cooperating with said rolls 45 cams the duties and operations of which will through slots in said table, the stocks 41* of be hereinafter explained; Fig. 10, a horizontal said folding-blades being all rigidly placed on section corresponding with Fig. 5 on theline one bar &3, which is pivoted into the arms M 10 10 thereof; Fig. 11, a transverse vertical of a rock-shaft The said folding-rolls 4O 40* and blades 41 are arranged transversely to the rolls 27 27* 31 31* and blades 28 32 for producing folds of the cut quarter-sheets or signature-sections in directions transverse to the two folds of the original sheet and parallel with the direction in which said quarter-sheets had been cut from the original sheet, thereby producing from each quarter-sheet or section a sixteen-page folded signature. For the purpose of preserving a parallel motion of the folding-blades 41 their carrying-bar 43 has affixed upon it an arm 47, which is connected by a radius-bar 48 with a fixed pivot 49 on the machine-framing.

For the purpose of first carrying the unfolded sheets from the feed-rolls 23 25 to the folding-plate 26, next carrying the once-folded sheets from the folding-rolls 27 27* to the folding-plate 30, and afterward carrying the twice-folded sheets to the slitters 37 and thence to the folding-table 39 there are employed two carriers 50 50, each consisting of a suitable number of cords or tapes. These carriers, though partly visible in Fig. 2, are more clearly represented in the corresponding diagram Fig. 13, wherein their courses are traced by arrows. Commencing at the lower feed-roll 23 the carrier 50 runs therefrom and around idler-pulleys 51 52 to near the first folding-rolls 27 27*. The carrier 50 runs over the folding-roll 27 and under 27*, thence over and under idler-pulleys 53 54, over one and under the other of the second folding-rolls 31 31*, thence over the foldingtable 39, returning round pulleys 55 on a rotary shaft 56, thence under the table 39, over idler-pulleys 57 58, under idler-pulleys 58*, and thence to the foldingroll 27. These carriers run continuously in the directions of the arrows shown upon them in Fig. 13 and may be driven in any suitable manner. 50 is represented as driven by the feed-roll 23 and 50 as driven by the folding-rolls 27 27* 31' 31* and by the shaft 56, all of which are driven positively by any suitable gearing such, for example, as is shown in Figs. 1, 2, 4, and 1.2. A spur-gear 59, Figs. 1, 2, 4, and 12, on said shaft 21 serves, as may be easily traced through Fig. 12, to drive the folding-rolls 31 31* and slitter-shaft 36 and the carrierrshaft 56. A bevel-gear 60, Figs. 1 and 4, on said shaft meshes with a bevelgear 61 on a side shaft 62, Figs. 1 and 4, another bevel-gear, 63, on which shaft meshes with and drives a bevel-gear 64 on the feed-roll 23. This roll is geared, through another side shaft 64*, Figs. 2 and 12, and the bevel-gears 65 66, with the folding-roll 27* for driving the folding-rolls 27 27*. The folding-rolls 4O 40* are represented (see Figs. 1 and 4) as driven by the same train of gearing which includes and begins with the gear 59, the said rolls all being geared by pairs of miter-gears 75, Figs. 1 and 2, with a shaft 76, Figs. 2and 12, which for driving it is furnished with the gear 77.

Forward of the folding-rolls 27 27* there is arranged over the carrier 50, as shown in Figs. 2 and 13, a supplementary carrier consisting of tapes or cords 67 and carrying pulleys 68 69 therefor for the support of the forward parts of the unfolded sheets during their presentation to the said folding-rolls and for the support of said parts during the first part of the first folding operation. Likewise forward of the second folding-rolls 31 31* there is arranged over the said carrier 50 a supplementary carrier consisting of tapes or cords 70 and carrying pulleys 71 72 therefor for the support of the forward parts of the sheets which have been once folded during their pre sentation to the latter folding-rolls and during the first part of the second folding operation. For driving the supplementary carriers 67 70 the shafts 68* and 71* of their pulleys 68 71 are furnished with gears 67* and 70*, which are included in the train illustrated in Fig. 12, which includes the gear 59. Over the supplementary carriers 67 70 there are arranged stationary guard-rods 73 for preventing the turning up of the forward parts of the sheets on said carriers, and on these rods 73 are stops 74 for stopping the sheets in proper positions for folding by the rolls 27 27* and 31 31*, respectively.

The folding-blades 28 32 41 may be actuated by any suitable means. For actuating them I have represented three cams 113 114 115 on the shaft 22, which receives constant rotary motion, as illustrated in Figs. 1, 2, 4, and 1.2,-

through its gear 59" from a gear 59 on the driving-shaft 21 and an intermediate loose gear 59. These cams are shown in Fig. 3, which represents a transverse section of the shaft 22 and side views of the cams. The cams 113 114 for operating the blades 28 32 are both alike. The cam 113 operates, through a rod 116, on an arm 117 of the rock-shaft 34, which carries the blade 28. The cam 114 operates for the purpose, through a rod 118, on the arm 119 of the rock-shaft 35, which carries the blade 32. The cam 115 operates, through a lever 115*, having a fixed fulcrum 120, on a rod 120*, which connects said lever with an arm 121 on the rock-shaft 45, by the arms 44 of which is carried the bar 43, which carries the blades 41. The cams operate to raise the blades; but the downward movements of the blades, by which the foldings are performed, are produced by springs 122 123 124 under the control of said cams, as is common in such folding devices. The spring 122 for producing said movement of the blade 28 is represented in Fig. 3 as applied to an arm 125 of the rock-shaft 34. The spring 123 for producing the movement of the blade 32 is repsesented in Fig.3 as applied to an arm 126 of the rock-shaft 30, and the spring 124 for ITO producing said movement of the blades 41 is represented in Figs. 1 and 2 as applied to an arm 127 of the rock-shaft 45.

The camshaft 22 is represented (see Figs. 1, 2, and 4 and also in the detail section Fig.

as carrying, besides its other cams abovementioned,'a cam 128 for lifting the feed-roll 25 at proper times, the said cam operating on a yoke-rod 129, connected to the arm 130 of the rock-shaft 130*, which carries the said feed-roll.

' So far as the machine illustrated has been hereinabove described it produces from one sixty-four-page sheet four sixteen-page signatures, and it resembles in all essential particulars a machine which is the subject of my application, Serial No. 181,980, for United States Letters Patent and by which the four sixteen-page signatures to make one sixtyfour-page signature are taken each from one of four original sheets. There is also in this machine (see Figs. 1, 4, and 5) arranged below the folding-rolls 40 40* an intermittentlymoving endless signature-carrier consisting of two parallel endless toothed racks or chains 80, furnished with pockets 81, running horizontally in a direction transverse to that of the endless sheet-carriers 50 50; but instead of the sixteen-page signatures passing directly from such folding-rolls to the carrier-pockets 81, as in that machine, they are in this first collectedin twos, inset one within another in two intermediate pockets 140 141, Figs. 1, 4, 5, and 10, and the two so inset in one of said intermediate pockets are first deposited in one of the carrier-pockets 81, and then While in the latter pocket they have inset within them the two which had been similarly collected in the other intermediate pocket. The-several carrier-pockets 81 are at distances apart equal to the distance between the several pairs of folding-rolls 40 40*. The two intermediate pockets 140 141 are at corresponding distances apart and are arranged, respectively, directly under those two of said pairs of folding-rolls designated 40*, which are next themiddle of the width of the machine, and the intermittent movements of the carrier 80 are so provided for and timed that its stoppage or intermissions occur with two of its pockets 81 under the two intermediate pockets 140 141 and the two pairs of folding-rolls 40' last pocket and consisting of a horizontal bar 97 or 97' and side pieces'98, firmly attached thereto, the said bars 97 of the carrier-pockets being pivoted into brackets 99, (see Figs. 1, 2, 4, 5,) which are rigidly attached to opposite links of the endless racks of the signature-carrier, and the said bars 97* of the intermediate pockets being pivoted at suitable fixed points on the machine. The pivots of the bars 97 of the rearward intermediate pocket 140 are represented as in fixed brackets 142, (see Figs. 5 and 10,) carried by the framing of the machine, and the pivots of the bars 97* of the forward intermediate pocket 141 are represented as in brackets 143 on one of the cross-pieces of the framing. The pivotbars 97 97* of the carrier-pockets and those 97" of the intermediate pocket 140 have applied to them, as shown in Fig, 10, between them and their supporting-brackets springs 111 and 111 by which they are kept closed at all times except when they are, opened by cams, as hereinafter described, for the delivery of the completed signatures; but the intermediate pocket 141 has no such springs, as both its opening and closing have to be effected in a positive manner by a cam. For the purpose of opening and closing the intermediate pockets and of opening the carrier-pockets the two members or halves of each of both the intermediate and the carrier pockets have affixed to one end an arm 100, and these two arms are connected, as shown at 101 in Figs. 1 and 5, by a pin in one entering a slot in the other, so that by'a pivotal movement given one member a corresponding movement is imparted to the other. The cam above mentioned for opening and closing the intermediate pocket 141 and cams for opening the carrier-pockets and the intermediate pocket 140 are all on ahorizontal shaft 108, which is arranged in fixed bearings at right angles to the cam-shaft 22 and receives constant rotary motion therefrom through a pair of miterg'ears 110. (Shown in dotted outline in Figs. 2 and 4.)

Between each of the intermediate pockets 140 141 and the pair of folding-rolls 40*, situated above it, there is in stationary bearings a pair of continuously-rotating rolls 144. between which one sixteen-page signature folded by said folding-rolls and another such signature folded by the adjacent pair of folding-rolls 40 to the right or left of it are carried together into one of the carrier-pockets and therein inset one within the other. The bearing for one of these rolls 144 has applied to it an adjusting-screw145 for the purpose of producing a suitable pressure to close the two signatures together as they enter the pocket. Said rolls are geared together and represented (see 146, Fig. 4) as geared with and driven by one of their respective rolls 40 For the purpose of carrying each signature folded by one of the pairs of folding-rolls 40 into the signature folded by its adjacent pair 40* and insetting it therein there are employed, as shown in Figs. 4 and 14, two sets of tape carriers 147 and 148, the set 147 running over the outer roll 40, under its corresponding roll Ail.

10 around one of the rolls 1&4, and around' .said carrier-that is to say, the pocket 1411 there are arranged (see Figs. 5, 10, 11) rolls 151, which receive the two signatures from the pocket 1 11 and inset them together into two signatures which had been previously deposited by the pocket into a pocket of the carrier which has been brought from the position under the pocket 1 10 to the position under the pocket 1 11. These rolls 151 serve the purpose of holding closely together the leaves of the signatures from the pocket 1&1 as the said signatures enter into those from the pocket 110. The said rolls are carried by two shafts 152, which run in bearings in the lower ends of two pairs of crossed levers 153, the fulcrum of which are two fixed studs 15 1, secured in the framing. The upper ends of said levers are connected by rods 155 with the opposite arms 156 of a rock-shaft 157, which is arranged in fixed bearings in or on the framing and in which there is an arm 158, which is connected by a rod 159 with a cam 160 (see Figs. 2 and 5) on the cam-shaft 108. For the purpose of producing a constant rotation of these rolls 151 in the proper direction the said rolls are geared, as shown in Figs. 1 and 5, with the rolls 1 14 through gears 161 on said rolls 1 141, loose gears 161* on the framing, loose gears 162 on said studs 15 1, and gears 163 on said rolls 151. The same rock-shaft 157 above described also carries an arm 164: for the purpose of opening and closing the pocket 1 11 at the proper time, as will be understood by referring to Fig. 5 and the detail view Fig. 15 on the same sheet, which represents a side view of the pocket. In these two views it will be seen that said arm 164. is connected by a rod 165 with an arm 166 on the pivot-bar 97 of one half or member of the pocket, and it has been hereinbefore described with reference to all the pockets how by the connection of the two pivot-bars by their arms 100 and the pin 101 the two members of a pocket are caused to move together for opening and closing their bottoms. A cam 167 (see Figs. 2, 5, and 6) on the shaft 108 also serves the purpose of opening the pocket 1 10 at the proper time, the said cam being connected by a rod 168 with one arm 169 of a rock-shaft 170, which works in fixed bearings in or on the framing and which carries a tappet-arm 171, which (see Fig. 5) strikes under an arm 172, provided on one of the pivot-bars 97* of the pocket.

The carrier-pockets are each furnished at both sides of their mouths (see Figs. 5, 10, 11) with holding devices, represented as bent fingers 173, for the purpose, after the deposit of chine-framing.

signatures thereinto from the rearward intermediate pocket 1 10, of holding open or apart the upper edges of the so-deposited signatures during the deposit thereinto of signatures from the forward intermediate pocket 1 11. These fingers are attached to small rock-shafts 17a, which work in bearings on the backs of the two members of the pocket. To keep these fingers, as shown in Fig. 5, overlapping the edges of the pockets at all times but when each of said pockets is presented under the intermediate pocket 1 10, coil-springs (see Figs. 10 and 11) are applied between their rock-shaft 174C and the side pieces 98 of the pockets. For the purpose of throwing aside the said fingers, as shown in Fig. 5, in that carrier-pocket which is under the intermediate pocket 140 their rock-shafts 17 1 are each furnished at one end with an arm 176, the end of which is in range with a lever-arm 177, fast on a rock-shaft 178, which works in fixed bearings in a stand 179 (see Fig. 1) on the ma- This rock-shaft 178 has another arm, 180, which has connected with it a rod 181, which engages with a cam 182 (see Figs. 2 and 7) on the shaft 22. A spring 182 applied between the arm 180 and the stand 179 acts on the said arm to depress the arm 177 to a position in which it is inoperative on the finger-arms 176; but at the proper times for the reception of signatures by a carrier-pocket which is stationary under the intermediate pocket 140 the cam 182 acts to raise the leverarm 177 and throw back the fingers 173 from the mouth of the carrier-pocket; but after the reception of the signatures by the latter the cam 182 allows the lever-arm 177 to be depressed by the spring 182 and allows the finger-springs 175 to throw the fingers over into the pockets and over the edges of the signatu res therein, which are thus held open for the reception of signatures from the pocket 141.

The racks 80 of the intermittently-moving signature-carrier are represented as running in stationary horizontal ways 82, forming parts of frames 83. carried by the main framing, said frames also containing or supporting the pivots 84, on which run the wheels 85, which carry said racks. The two racks are geared together to run in unison by spur-gears 86 and 9 1, Fig. 1, on shafts 87 and 93, which run in fixed bearings in or on the framing. The movements of the carrier are obtained one from every revolution of a cam 89 on the camshaft 22. The means through which the cam 89 drives the carrier-racks are illustrated in Figs. tand 16. Said cam acts against a lever 90, which is pendent from a fixed fulcrum 90' and the lower end of which has pivoted to it one end of a rack-bar 91, which engages with a pinion 92. fitted loosely on the shaft 93,- hereinbefore mentioned, upon which are the two spur-gears 94;, which mesh with the racks. There is also fast on said shaft 93 a ratchetwheel 95, which is engaged by a pawl 96, carried by the pinion 92, so that by the move-- siXty-four-page signature which had been collected in the carrier-pocket under the intermediate pocket 141 there is employed a stapler, (designated as a whole by the numerals 183 184 185,) the said stapler occupying such a position relatively to the signature-carrier, as shown in Figs. 4, 5, and 10, that the so-collected signature will be brought to it by the next movement of the carrier. This stapler may be of any suitable kind; but I prefer to use and have represented one substantially like that which is the subject of United States Letters Patent No. 613,210, which is well known, and I have inverted its parts from the position shown in that patent-that is to say, I place the parts 183, which contain and carry those parts which form and drive the staples, under the operative run of the carrier and place the anvil or clenching member 184 above, and instead of making said member 184 stationary I attach it by arms 185 to a rock-shaft 186, which works in fixed bearings in brackets 187 'on the framing and provides for dropping it into the pocket, as shown in Fig. 4, at the time for stapling and lifting it out again and holding it up high enough to permit the movement of the carrier and pockets at other times. This movement of the anvil is effected by a cam 188, Figs. 1, 2, 4, 5, and 8, on the shaft 108, the said cam operating through a rod 189, connected with an arm 190 on the rock-shaft 186. The stapler thus arranged inserts the staples from the outside of the fold of the signature and clenches them on the inside of the fold. As this stapler, except its inversion and its movable anvil, above described, constitutes no part of the present invention, no further description of it is necessary; but as it is to some extent represented in the drawings I will, to avoid confusion of its parts with other parts of my machine, mention that its rotary shafts 193 are driven, as shown in Figs. 2 and 12, by a gear 194 on the rotary cam-shaft 22, gears 195 on said rotary shafts, and intermediate gears 196 197 198.

At a distance beyond the stapler equal to the length of the movements of the carrier there is a packer or receptacle of any suitable kind for the completed and stapled signatures; but as that constitutes no part of the present invention only a packing-table 191 and guides 192, erected thereon, for the reception of signatures are represented in the drawings. For the purpose of opening each carrier-pocket after its arrival in proper relation to said packer or receptacle one of the pivot-bars 97 of each of said pockets has aflixed to it a rearwardly projecting arm 102, which by the movement of the carrier is brought, as shown in Figs. 4 and 5, over a roller on the end of the arm 103 of a short rock-shaft 104, which is arranged in a fixed bearing in or on the framing and which has also another arm, 105, which has connected with it a rod 106, actuated by a cam 107 on the shaft 108.

Having now described the several parts which constitute my invention, and their mutual relation, I will now briefly recapitulate their operation in regular succession in folding the sheets and cutting them into sixteenpage signatures and the collection of these signatures into siXty-four-page signatures.

I have mentioned in the introductory part of this specification that a machine embodying the present invention is capable of producing the siXty-fourpage signatures from four sixteens all made out of one sixty-fourpage sheet or from two sixteen-s made out of one such sheet and two out of another. This change of operation is effected by simply shifting the cam 160 from one to another of two positions relatively to the cam 167 on the shaft 108. I will first describe the operation in which the sixteens are all taken from one sheet, the said cam 160 being represented in the drawings as set in position for that operation--that is to say, in rear of 167 in the direction of the rotation of the shaft 108, which is indicated in the several figures by arrows.

The siXty-four-page sheets being successively fed by the rolls 23 25 are carried singly to the folder 27 27* 28, and each, after having been thereby folded transversely to its line of travel, passes on to the folder 31 31* 32, whereby it is folded the second time parallel with the first fold. The twice-folded'sheet passes thence over the slitter 37 to be cut transversely into four sections, which, passing to and through the folder 40 40* 41, are folded into a set of four sixteen-page signatures, two of which signatures, folded, respectively, by the two pairs of rollers 40*, are received by the rolls 144 and deposited one in the intermediate pocket 140 and the other in the intermediate pocket 141, the other two, folded by the rolls 40, being taken by the carriers 147 and 148 to the rolls 144 and dropped by the latter rolls one into each of the signatures which had been previously deposited in said pockets 140 141,

two sixteen-page signatures inset one within the other being thus collected in each of the pockets 140 141. The pocket 140 is opened by its cam 167 before that 141 is opened by its cam 160, and the two signatures from the pocket 140 are therefore deposited ina pocket 81 of the carrier 80 before the pocket 141 is opened to deliver its two signatures, the latter opening not taking place until after a move: ment of the carrier has been made and the two signatures delivered, as above described, into the carrier-pocket from the pocket 140 have been brought by said movement under that 141. The two signaturesdelivered from 141 1 are thus inset into the two previously delivered 1 from 140, thereby making a sixty-fenr-page l signature, which, passing on to the stapler,v is completed by the operation of the latter. In these operations of the carrier and pockets every movement of the signature carrier brings one of its pockets 81 under the pocket 1 1&0 to receive two sixteen-page signatures therefrom, and the next movement brings these two signatures under the pocket 141 to receive therefrom two other similar signatures. Every movement of the carrier delivers a completed sixty-four-page signature.

W hen it is desired to make the four sixteen-page signatures for one sixty-four-page signature, two out of one and two out of another of two siXty-four-page sheets which are fed successively to the folders 27 27* and 31 31 and 40 10, 10 40*, the only change necessary in the machine is to place and set the cam 160 in such position relatively to that 167 that both cams operate together to open the two intermediate pockets 1 10 1&1 sin'iultaneously. Then every time the carrier stops and the said pockets open each of said pockets delivers two signatures to the pocket of the carrier beneath it, and everytwo signatures delivered from the pocket 1&1 are inset into the two previously delivered into a carrier pocket from the pocket 14:0. In this case every two signatures inserted into and first delivered by the pocket 14.0 come from one of two sixtyfour-page sheets fed to the machine, and every two inserted into the pocket 141 and afterward delivered therefrom into the two from the pocket 140 come from the next succeeding sheet, the two signatures from one sheet deposited in the pocket 140 being delivered into an empty carrier-pocket, which after receiving them is by the next movement of the carrier presented under the pocket 14:1 to receive two more signatures from the succeeding sheet from the latter pocket, thereby completing the sixty-fonr-page signature.
